Pokemon: Vanilluxe
Type:
BST: 81 (+10) / 90 (-5) / 80 (-5) / 130 (+20) / 85 (-10) / 104 (+25) | BST: 570
Abilities: No Guard / Snow Warning /
Tinted Lens
New Moves: Nasty Plot, Focus Blast, Hyper Voice
Removed Move: Sheer Cold (Because of No Guard, otherwise just quick ban this combo)
Justification/Niche: Ice / Normal is not an ideal type, consider the fact that 4x weakness to Fighting is already a death warrant. With a reasonable Speed of 104 which help for Choice Scarf, and access of Nasty Plot, as well as more useful Abilities with No Guard and Tinted Lens, Vanilluxe is more than just floating ice cream Pokémon. Optimized Hariyama, faster Fighting-types and Mach Punch will give it nightmares, but you can set up a hail with Snow Warning for no miss Blizzard, or use No Guard so that Focus Blast will not be Focus Miss especially considering the Steel-types, and you always got Freeze-Dry to break thorough the likes of non-rain Mega Swampert, Toxapex and other notable Water-types.
Pokemon: Volbeat
Type:
BST: 80 (+15) / 123 (+50) / 70 (-5) / 100 (+43) / 70 (-15) / 127 (+42) | BST: 570
Abilities: Technician / Refrigerate /
Prankster
New Moves: Leech Life, Surf, Ice Beam
Justification/Niche: Ice / Bug will be a horrible defensive type, and I was successful with the Lunatone submission for Rock / Psychic, so I try to do similar treatment for Volbeat (there just isn't many Bug-types who would logically go along with Ice). It can work as Physical, Special or Mixed (provided that you got Tail Glow for the latter two). While Refrigerate may be the most used Ability for Double-Edge and Quick Attack, Technician can be used if you want to use Hidden Power coverage. U-Turn is still there for pivoting, and a base Speed of 127 is pretty fast on its own.
Pokemon: Weavile
Type:
BST: 70 / 120 / 65 / 110 (+65) / 80 (-5) / 125 | BST: 570
Abilities: Mold Breaker / Pressure /
Sniper
New Moves: Stomping Tantrum, Drain Punch, Frost Breath
Justification/Niche: Weavile is not enough viable to be wholesome OU, so I will simply fix up its bad Special Attack into useable (and to make Nasty Plot more significant) as well as better Abilities. Mold Breaker helps Weavile to penetrate Unaware, Disguise and other non-contact Abilities, while Sniper can stack well with Shadow Claw, Night Slash and makes Crits more powerful and punishing (Frost Breath might be fun to use too). Nothing else to say, but the raised Special Attack will do permit more unpredictability than Weavile would ever be outside of this Pet Mod.
